Background technique
Its output frequency of conventional electric power generation unit is synchronous with the revolving speed of engine, and inverter generator group is by generator
The AC rectification of sending converts thereof into the alternating current of required frequency (generally at direct current, then by the circuit of inversion
50HZ and 60HZ), thus the revolving speed of engine do not need it is synchronous with output voltage, it was found from the natural working condition of engine
Then best torque point is higher for the smaller engine of displacement per cylinder, it is however generally that the engine best torque point of 50CC or so is at every point
Clock 4500 turns left the right side, and the engine best torque o'clock of 100CC or so turns left the right side 4000, and 200cc is then in 3500 or so, 400CC
Engine is then about 2500 or so.It is understood that the power of engine is that revolving speed multiplies torque, if by the engine of 50CC or so
Its revolving speed of synchronous generator as manufacture 50HZ is 3000 revolutions per seconds, then the efficiency of engine and power are not all played much
Out, being used as manufacture inverter generator group just i.e. can with the engine of same discharge capacity using high-revolving best torque
To produce more powerful generating set, efficiency can also be significantly improved, if instead advantage be it will be apparent that using

Rocker arm and valve activity, still have very strong noise when running.And at present in small-sized inverter generator field for noise abatement
It is required that higher and higher, so in order to further eliminate noise, using overhead cam and corresponding transmission mechanism as transmission power come
Replacing existing valve opening and closing driving mechanism is that the design in current small-size double cylinder generating set is dominated.But it equally also brings as follows
The problem of:
It is well known that known generating set is based on lightweight and the simplified design consideration of structure, internal engine
Lubrication usually all using lubrication of splashing, but the disadvantage is that lubricant effect is often poor, particularly with starting using overhead cam
For machine, each parts in cylinder head are often not achieved in the machine oil thrown away from crankcase inside crankshaft, exist lubrication less than
The problem of.On the other hand, existing lubricating system is often all based on designed by original tappet driving mechanism, and structure is complicated, example
It such as needs to design oil return hole on tappet, influences cylinder head circularity and leakproofness.
In addition, as the engine speed increases, the resistance that crankshaft gets rid of oil generation is increasing, biggish power damage is generated
It loses.Meanwhile crankshaft gets rid of oil will also make machine oil premature ageing, and is easy to be mixed into bubble among machine oil.Therefore existing small-size double cylinder
The lubricating system of generating set is simultaneously not suitable with its development, it would be desirable to seek more efficiently, reasonable and reliable lubricating system.
